7 LUBRICATOR;

Application filed October 17, 1923. Serial Massages,

My invention relates to lubricators such as are adapted to be p and driving boxesof railroad-rolling stock and consists in an improved mechanism by means' of which the" lubricant may be pumped from a suitable reservoir to-thesurface of'the journal to which the device is applied. 7 a 7 a The object of my invention is to provide a; simple reliable and durable pump'operating mechanism and one in which thespeed and capacity of different pumps may be variedby the change of a single part withouta'fl'ectingtheremainingparts V I In prior patents issued to me, for instance, Nos. 1,378,452, 1,412,739,1,412,740,1,416,710, 1,423,850, and 1,423,851 I have disclosed pump, operatingrnechanismsin which shittingot the journal longitudinally eras axis operates the pump; 7 I

While such constructionsare sufiiclent for ditions inwhich the projection of an operatingmember to the exterior-10f the box is objectionable and in which the movement of the, pump plunger, intone direction should be quicker than that provided by the shifting movement ot-the journal through the box, whichmay be very, slow. Otherobjectsof my present invention are to satisfy these requirements. a

In the accompanying drawings which illustratemy invention-- Figure 1 is a vertical transverse section through a 101111131130 which my lubricator is applied.

Figure 2-is avertical longitudinal section through my lubricator showing the journal. Figures 3 and 4 are vertical transverse sections corresponding to Figure'l but taken through'modified embodimentsof my invention.

Figure 5 is .a detail illustration of the: pawland'lever shown in Figure 1, but 1ndiournal.

In Figure 1 the lower portion-of thejournal lubricatorbodyl forms a lubricant reservoir 2 andsuitablehorizontallsurfaces 3 and 4 on the car-ryspringso which support a pan 6 adjacent-to; the journal A, which p in i v. waste; or other lubricant retaining and distributingzmaterial. v 7

Extending; from the, lower portion of reservoir 2 to a central opening. in pan 6 is a passage? equippedwith an intake valveused in the journalboxes adapted tel bepacked with 8 and a check .valve 9 between 'whichis located themouth of a pump cylinder 10, I

the piston or plunger- 11 of which cylinder is slidably mounted therein andin a suitable bearing 12 spaced from the cylinder and forming. a seatfor a spring 13 which tends to force the piston through its discharge stroke to an advanced position in the cylinder. The piston is operated through its intakestroke by means of a cam 14 and a bell crank 15 and a simple lever 16. The cam 14 is fixed upon a rotatable shaft 17 journaled in housing land carrying spaced disks 18 which partially support a roller 19 adapted to engage the surface or journal A above a horizontal line passing through the journal axis andtobe frictionally rotated by the journal soas to drive disks'18, rod 17 and cam 14'. v 7 i i A rod 20 passes through arelatively large axial openin'giin roller 19 and retains the roller 1n operative position without limiting its actual position leaving the roller free to accommodate variations in theiaxes and relative positions of the VdiskslS and journal A. Obviously rotation of cam 14 in the direction indicated by. the arrow ,in 'Figurel will move the-horizontal legof crank 15' downwardly. A weighted pawl 22 pivoted on the inner end of this leg of the bell crank engages a pin 23 on the'belllcranksoas to be held against pivotal movement in one direction anddownward movement of the bell crank causes the end of'this pawl 22 to engage the inclined surface on the end of lever 16 thrusting the same to the left and retracting piston 11 through cyl' inder 10. As soon as the pointv24 upon lever 16 rides over the top of pawll22 the lever is, released-and spring 13 will quickly move it and piston llto their original positions thereby providing the pump with a quick discharge stroke forcing lubricant upward lyv along passage 7 to the surfaceof the When the vertical leg "of bell crank 15 isreleased by thefcain aspring 25 returns it to its original positionand in so doing: pawl 22 1s turned on its pivot until its lever-engaging endi-hasridden over. point 24 when it will return to its normal. position in engagement with 1 pin 23. Obviously movement of the cam in the. opposite direction willlraise the horizontal leg ofthe bell 1 [l0 crank from the position shown in Figure 1 without operating the pimp.

Itwill be noted that dy, 1 isprovided with an upwardly and inwardly extending portion which houses the cam, disks and roller and protects them from damage before and during their installation and operation in the journal box.

In the construction shown in Figureikiith'e pump cylinder and piston 31 are vertically disposed and the upper end of the piston is directly engaged by cam 32 and will be operated by movement of the cam in either direction. In this operation the quickness of the return of the plunger to the position shown will be limited'bythe speed at which the cam isdriven' and by the angle necessary to permit the piston to be depressed. In this construction the ren'iaining features'of the device correspond to those illustrated in Figure 1 although somewhat differently arranged,

In the construction shown in Figure ii: a one way drive for the pump is illustrated inivliieli the cam 33 is rotated by a roller 34 similar to the cam and roller arrangement in Figures 1, 2 and 3. The bell crank 35 which is operated by cam 33 is directly connected to horizontal piston 36 vhich is disposed similarly to piston 11 in the'constructionshown in Figure 1. Here a quick return or discharge moven'ient of the piston is provided for by the contour of cam It is obvious that this quick movement of the piston may be provided for the intake stroke insteadiof the discharge stroke if desired. In the construction shown in Fig ure this may be accomplished by reversing the cam and cxtendingthe horizontal arm of thebell crank to the right instead of to the left and moving its pivotal pointaccordingly andm the construction shown in F1g- .ure 1 by reversing the inclined end oflcver 16 so" that it faces the left instead of the right and by reversing pawl 29 on the bell crank and moving it to the other side of lever 16; j The engagement of the cam andboll crank in theconstruction shown in Figure dis so arrangedthat reversal of the direction of rotation ofthe cam from that indicated by the arrowwill be accommodated. An L- shaped contact finger 39 is pivoted on the to the dotted line posit-ion and permit the cam to rotate Without operating the bell crank. I

.In the construction shown in Figure 4 the .intake valve is omitted and'a number of small openings 37 are provided in'the wall of the pump cylinder. With a slow intake stroke of the'pistonithese openings will admit lubricant sufliciently quick enough to "with said journal and member for actua fillthe cylinder. With the quick discharge stroke of the piston the check valve 38 will be lifted and a substantial amount of lubricant forced by the same and the piston will pass openings 37 before any substantial amount of lubricant has been expelled through them.

Ina'ny of these constructions any obstruction of the device due to clogging of the pump or positive engagement of the parts caused by reversal of the direction of rotation of the journal will simply result in the rotation of the idleroller without corresponding rotation of the disks thus avoiding anyinjury to the device. j

In all of my above described constructions the speed and capacity of the pump may be readily controlled by varying the weight and .size of the loose roller contacting with the reservoir, a lubricantsupply pump, a rotatable member for operating said pump, and a floating roller carried solely by said journal and member in frictional contact i g said member from said journal.
